Probabilistic risk assessment (PRA) is a systematic and comprehensive methodology to assess the risks of complex systems. PRA is an essential part of the safety management in safety-critical industries, such as the nuclear industry, power production, process industry and transportation. PRA provides vital information to evaluate the importance of critical functions, identify weaknesses in technological systems, and optimise and balance design, operation and maintenance. In the nuclear domain, PRA is used to continuously find ways to improve safety, justify plant modifications, optimise annual maintenance revisions and fulfil regulations.
SimulationStore is a web portal that provides an easy access to VTT’s and its partners' Modelling and Simulation (M&S) offering.
- In these pages you can find information about the computational tools and related M&S services provided by VTT.
- By registering to the web pages you can download the installers of the computational tools and different plug-in products.
- In addition you can manage your own licenses related to these products.
- Some of the VTT’s computational tools include Simupedia features. It is also possible to publish interactive models to the SimulationStore using this functionality.
Modelling and simulation is a present-day way to understand and improve processes to meet the increasing efficiency, safety and environmental demands. Simulation has become an important enabling technology in decision-making, engineering and operation, covering the whole life span of a production system.
Model checking is an efficient formal method for the verification of hardware and software designs. Based on model checking, VTT offers a service for verifying that automation system software design fulfils stated requirements. The difference to more common verification methods (like testing or simulation) is that all the possible executions of the system model are taken into account. Exhaustive analysis means that hidden design errors can be found in systems that have already undergone verification through conventional means.
KilnSimu is used in several industries. Though the technology of rotating drums has been available for over 100 years, it has not been replaced, but remains in active use in many of its traditional applications. The rotary drum provides an effi cient means for both heat and mass transfer in the processing of slurries and other condensed mixtures.
SULCA software allows the user to perform Ecodesign and various kinds of Life Cycle Assessments (LCA). With SULCA, the environmental, carbon and water footprints can be calculated in a transparent and user-friendly way. Tool supports the evaluation of sustainability and environmental performance of a product,process, technology or any other system.
Future models in process chemistry will increasingly be based on a multi-component, multi-phase Gibbs energy approach. ChemSheet is the foremost pioneer in Gibbs’ian process modelling. Taking advantage of unique immaterial constraints, ChemSheet handles reaction rate controlled chemical systems, multi-phase membrane systems, complex materials with surface phases, and much more.
To gain further benefit around the use of SULCA there are various kind of services and expertise available.
To achieve most beneficial use of SULCA and services supported by it, a multidesign approach can be applied (figure below). We provide comprehensive sustainability assessment services with over 20 years of experience, and offer our customers information on their environmental impacts and overall environmental performance. Our expertise is in finding optimisation potentials of new products, industrial processes and technologies. We cover environmental, social and economic aspects of sustainability.
Training on the use of the SULCA software is available from the supplier. Training of SULCA software can be one day or more, and can be ordered along the purchase of the licences of SULCA or separately. The training is provided by VTT LCA expert and it can take place either at Customer’s place or at VTT . The content (e.g. SULCA basics, example cases and/or customer’s cases), place and time should be agreed together in more detail.
System dynamics is a methodology for understanding the behaviour of complex dynamic systems belonging to different domains. Simantics System Dynamics is a free, open source system dynamics modelling and simulation software. The software has an intuitive and easy to use Eclipse based graphical user interface which allows you to configure the whole model structure graphically. In addition to supporting all the common system dynamics modelling operations, the software includes many advanced features, such as structural reusable components, multidimensional variables, and sensitivity analysis.
